Snail actually follows the line!
The 21st century is said to be the age of robotics. Tamiya explores this new trend
with the release of an assembly robot snail. The Line Tracing Snail uses a special
LED sensor to detect a black line (magic marker, etc.) drawn on a white
background. It uses two small motors and rubber tires to slowly but surely move
forward and turn. The body of the snail is made of transparent (HIPS) plastic to
allow viewing of the intricate mechanisms inside.
This clever snail comes with Infrared LED and Photo Transistor
The snail emits an infrared light from the Light Emitting Diode on the underside
of its chassis. A photo transistor picks up the reflection of the infrared light to
distinguish black from white surface. Transistor sensitivity can be adjusted to
adapt for a variety of paper sizes and line widths.
Cute little guy ain't he!
Snail eyes move in-synch with tires. Snail capable of low/high-speed setting.
Low-speed mode suitable for fine lines and narrow areas. High-speed works best
for wide areas and thick lines.
Robotics made simple and fun!
Snail follows the line without fail. Feel free to line up a family of snails for even
more line tracing, robotic wackiness. Opaque body can be painted for added
style. (picture features snail painted with Mini-4WD fluorescent paint).
How to draw a snail course...
Draw a line on a white surface with an oil based black pen. Tamiya Paint Marker
is ideal. Draw curve radius over 8cm, line width over 3mm.
